## What is Phosphor Display?

Phosphor simulates a physical LED dot-matrix display on your screen. Send text, images, and animations to a virtual LED panel with authentic phosphor glow, dome highlights, and other visual effects.

Control the display over your local network via a built-in HTTP API, or use the web admin panel from any browser on the same network. Supports scrolling text, static images, GIF playback, clock mode, and several generative animations.

Features:
- Metal-based SDF renderer with per-dot glow
- Full RGB per-pixel grid control
- 12 visual effect toggles (phosphor persistence, scanlines, CRT curvature, and more)
- Built-in web admin panel with image upload
- HTTP API for local network automation
- Clock mode
- Generative animations: rain, plasma, Game of Life, matrix, bouncing dot
